zone

Done a fair bit of reading and spoke to numerous plumbers/heating engineers and I get so many different answers to my question. By nature I'm a pretty inquisitive bloke and like to know how things work and if its the best way to do things. So my first question is does a single zone UFH setup...

Hi, I'm a complete novice to UFH so excuse my ignorance! I've just had underfloor heating installed and an area of the ground floor is not heating up. The thermostat is set to 21 but it isn't getting past 20, and that's due to heat from other zones within a large open plan ground floor. The...

Advice needed please: I have an UFH installation as part of my main CH system. The UFH will never be required in isolation to HW or main CH, therefore keen to wire it completely independently of boiler and main wiring. All I want to achieve is the following: A new Room stat (in the location...

Hi There Currently using a Panasonic Air to Water UFH heating system in a new build and appear to have some gremlins in the system 1 - I've noticed that the kitchen zone is always hot if any other zone in the building is on. What could be causing this? Additional info - I think it is not...

Hi, I have a 2 Zones for my central heating. I have attached the picture of the Zones. I wanted to move the "hallway rad Zone 2" to Zone 1. From looking at the piping. I think I can just move the "hallway rad Zone 2" pipe (thin white one) to Zone 1 so it gets the hot water from Zone 1 when the...

Interesting question and one I’ve never even thought about until I messed up today. This might be a bit long…. I’ve got a multi fuel system on the go, gravity primary’s for hot water off Rayburn, big biomass boiler, air source is involved for the floors , pumped heating split into 5 zones blah...

Open vented fully pumped oil fired system. Works well but occasionally (every few days or do) loud throbbing noise from pipes directly above boiler. Goes away if system switched off and then immediately on again. New pump and no benefit from replacing zone valves. Any ideas gratefully received

Has anyone seen this configuration before with zone valves installing under the floor in the joist area with an access trap. Not ideal I know. Is for zoning a downstairs drop system and upstairs 15mm up though the floor. Boiler in the kitchen with pipes exiting upwards from the boiler via stand...

Hi all, At our old flat, we had a combi boiler which dealt with heating and hot water without an additional tank. There was an external timer next to the boiler, and a room thermostat (manual) in the hallway. I was able to replace the latter with a receiver and wireless (not smart) thermostat...

Hi all. First post. I have a JG UH3 wiring zone and I've noticed that the UFH pump always comes on when the HW 'circuit/thermo' is triggered. Hence - rather than just heat the water in the tank - I also heat the UF circuits. I can't see a way to avoid this - it may be the way the circuits...

There's power going to the valve head but the motor won't activate to turn the spindle to open the valve. The manual override will not activate the valve either. Should I replace the valve powered or Whole valve unit with pipe/spindle attached. My initial thinking the valve motor died and I...

Hi I want to set multiple HR92 on a single zone on my Evohome system but the documation leaves a lot to be desired so I would appreciate some help. This is especially true as the information I have found relating to multiroom says that the Heating type should be set to "zone valve" rather than...

Hi, my gas hob needs replacing but I'm told first the existing cooker hood must be raised as it's 70cm instead of 75cm above gas hob as per new regulations. Is that right?

Hi, Looking for some advice please. I live in france. We have a house with an attached cottage. We have no heating in our house but the cottage has a combi boiler and central heating rads. Seeing as this cottage is rarely used in the winter it seems daft not to add some rads to the boiler for...

Hi I have 3 zone valves, one per floor. I am having an Evohome system fitted so that I can get better control over the room temperatures. The exisiting zone valves will no longer be required and so it would make sense for them to be removed and replaced by pipe. The main issue is that a...

Can I run a motorised zone valve and room thermostat from a 240V supply to control a single radiator when the heating is on? Meaning the valve will be open when the room is below the temperature set on room thermostat without turning the boiler on / valve will close shutting off flow to a...

What are the best zone valves in your opinion? I mostly fit honeywell but as prices creep up I am thinking are they any better than danfoss, drayton EPH?

So I have just added an underfloor zone to a house extension. Boiler is Worcester Greenstar 30Cdi. has a Comfort II RF stat fitted that controls the radiator zone. I have added a zone valve to my new zone and used the 230V side of the control board to fire the boiler. the boiler fires fine but...

Hi all, Fitted a Worcestor boiler ( customers choice) got three zones ( two heating circuits, plus unvented) Would normally use heatmiser in this scenario but customer looking for budget option, any ideas? Thanks, Matt

Hi, I am about to add my underfloor heating to hive. I was informed I would need a multizone receiver and thermostat. upon further investigation Ive been informed I only need a standard thermostat and receiver. is this correct?
